Determining, setting, or changing the external LU cache mode
You set the cache mode when you define external LUs. HP strongly recommends that you set cache
mode to Disabled for external LUs. For instructions on mapping external LUs in a new configuration,
see
.
CAUTION:
Before you delete any LUs that you want to remap, carefully record necessary
configuration information. If you remap existing LUs with changed configuration settings (other
than cache mode), you can lose access to the LUs and the data they contain.
Determining if the cache mode is disabled
If you have an existing configuration and need to determine if your external LUs are configured
with cache mode disabled, follow this procedure:
1.
In the Remote Web Console main pane, click the External Storage button in the left pane. The
LU Operation pane appears.
2.
In the Device tree, select an external device group.
3.
In the Device list, check the Cache Mode setting (

enabled, you should change it to Disabled.

If you need to change the cache mode for existing external LUs, you must delete and remap the
external LU path and definition.

Before you delete any LUs that you want to remap, carefully record necessary
configuration information. If you remap existing LUs with changed configuration settings (other
than cache mode), you can lose access to the LUs and the data they contain.
